Patent GB-190427702-A (GB)
Title: Method of Winding for Asynchronous Electrical Machines for producing a variable number of Poles in the proportion of 1 : 2.
Filed: 1904-12-19
Granted: 1905-03-02
Abstract: 27,702. Siemena-Schuckert-Wertte Ges. Feb. 13, [date applied for under Patents Act, A.D. 1901]. Armatures; dynamos, regulating; field magnets; motors, controlling.-Relates to a winding for asynchronous machines so arranged that the number of poles can be changed. In the German patent No. 138,854, a loop - winding arrangement is described, the steps y1, y2 being obtained from the formulµ y1 =2SŒb/k + 1 and y2 = 2SŒb/k - 1 where S = number of poles, b = a number chosen as that 2 S is divisible by k, and k a number intermediate between the lower and higher number of roles. In the present arrangement, a wavewinding is employed, and the pole numbers may be changed in the proportion of 1 : 2. The two steps y1, y2are made unequal, e.g. in Fig. 2 an armature is shown with 54 bars which with a three-phase current can be changed from a 4-pole to an 8-pole machine. With four poles about fourteen bars correspond to a pole division ; with eight poles about seven. The step y1 is chosen intermediate between these, say 11, and the step y2, 17, the two steps being together equal to about two pole divisions. The winding can be traced from A (the 1st phase) to 1, 12, 29 and so on. By connecting the supply at A, B, C four poles are obtained, and by connecting also at D, E, F eight poles, the winding being thus series or seriesparallel. Instead of the connections A, B, C being equally spaced, the arrangement shown in Fig. 4 may be employed. In this 72 bars are employed, and the steps are 9 and 15 respectively. The tappings G, J, L give six poles, and by connecting also H, K, M twelve poles. Figs. 5 and 6 show the winding of Fig. 2 in a different diagrammatic arrangement, the phases flowing through the coils being indicated by the numerals I ... III. A four-pole arrangement is shown in Fig. 5, and an eight-pole one in Fig. 6. Figs. 7 and 8 show a method of obtaining the same result with three connections in each case by merely shifting the connection from the points N, O, P to the points Q, R, S. The windings are divided into two groups for each phase, or the number of groups may be generally obtained from the formula 2 a m, in which a represents the number of current branches per phase, and m the number of phases, a preferably being 1.

Granted: 1906-06-14
Abstract: 24,621. Gianoli, L. A. Dec. 2, 1904, [date applied for under Patents Act, 1901]. Magneto - electric machines; armatures; field magnets.-In an ignition magneto for explosion motors, the magnets are constructed with adjustable pole-pieces for advancing and retarding the sparking, and are fixed by means of clamps. An electromagnetic circuit-breaker is employed in connexion with the armature to give a spark of the same intensity irrespective of the speed. The armature d, Figs. 1 and 2, is provided with two superposed windings e, f, the former of which is connected at one end e' to the magneto body and at the other end to an insulated conducting- piece g, Figs. 2 and 3, forming part of the circuit-breaker. The winding f is arranged in the sparking circuit, and acts as a secondary transformer winding to the winding e, to which it is secured at one end e<2>, the other extremity passing through a duct in an insulating-tube r and terminating in contact with a button f<3>, which rotates in contact with a conductor r<2> communicating with the sparking device. The movable pole-pieces c are fixed upon two caps s, s<1>, which may be turned by means of a handle t. The magnets a are embraced by clamps v which secure them to the fixed pole-pieces b, the tension of the clamps being regulated by means of screws x and nuts y. Alternatively, the clamps may be fixed upon the end piece z, and the tightening performed from beneath the magnets. A condenser h is placed in shunt with the primary winding e through the medium of a brush i bearing upon the plate g and carried by a terminal i<1>. The circuit-breaker comprises a brass plate j supported by non-magnetic springs k on a plate l secured to the armature. The plate carries on one side two blocks of soft iron placed opposite to projections d<2> on the armature, and on the other side a platinum block m which breaks contact with a platinum screw n on the part g when the plate j is attracted by the armature. The plate j is always attracted at a given excitation of the armature irrespective of the speed. As the speed increases, the circuit is therefore broken sooner and sooner, thereby producing an automatic advance in the sparking. The extremities d' of the armature are connected by plates l, o supporting the armature axes r, p.
